+
+
+## Configure custom indicators
+Microsoft Defender ATP for iOS enables admins to configure custom indicators on
+iOS devices as well. Refer to [Manage
+indicators](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/manage-indicators)
+on how to configure custom indicators
+
+## Web Protection
+By default, Microsoft Defender ATP for iOS includes and enables the web
+protection feature. [Web
+protection](https://docs.microsoft.com/en-us/windows/security/threat-protection/microsoft-defender-atp/web-protection-overview) helps
+to secure devices against web threats and protect users from phishing attacks.
+
+>[!NOTE]
+>Microsoft Defender ATP for iOS would use a VPN in order to provide the Web Protection feature. This is not a regular VPN and is a local/self-looping VPN that does not take traffic outside the device.
+
+
+>[!NOTE]
+>**Battery Consumption by Microsoft Defender ATP for iOS**
+> Battery usage by an app is computed by Apple based on a multitude of factors
+including CPU and Network usage. Microsoft Defender ATP uses VPN in the
+background to check web traffic for any malicious websites or connections. Every
+network packet from any app goes through this check and iOS
+wrongly accounts this in computing the battery usage of Microsoft Defender ATP.
+This gives a false impression to the user. The actual battery consumption of
+Microsoft Defender ATP is much less than what is shown on the Battery Settings
+page on the device.
